Do you prefer working in a team environment or alone?

Starbucks is very much a team environment, and the interviewer needs to know that you will fit in. However, it's not a bad thing if you work well by yourself, and you should feel free to mention this trait in your answer. The interviewer is trying to get a feel for your personality and how you interact with others.

You may work well without the need for much management or direction, or perhaps you are better driven by a collaborative and team-led environment. Either way, be honest with the interviewer about your preferences and emphasize that you can adjust to either style.
